Biography
Louis was born in 1304 to Louis I of Nevers and Countess Joan of Rethel, and he was the grandson of Robert III of Flanders. He succeeded his grandfather on his death in 1322, and in 1320 he married Philip V of France's daughter Countess Margaret of Artois. Although the County of Flanders was economically-dependent on the Kingdom of England, Louis decided to side with the Kingdom of France in the Hundred Years' War, and he was killed at the Battle of Crecy in 1346.
